• Use PPB 30 O, PPB 30 K ventilation units
only outside protection zone 0.
• Use PPB 30 RC ventilation units only outside
protections zones 0 and 1.
• Observe electrical supply line to suit unit vari-
ant:
PP 45 O / PP 45 K: Control cable type J-Y (ST)
Y 2 x 2 x 0.8 mm. Max. 25 m from star point, up
to star point max. 4 m.
PP 45 RC: NYM 3 x 1.5mm²
PPB 30 O / PPB 30 K: Control cables: Type J-
Y (ST) Y 2 x 2 x 0.8 mm. Max. 25 m from star
point, up to star point max. 4 m. Mains connec-
tion and 230 V input: type NYM-J 5G1, 5 mm²
• Exhaust air mode on PPB 30 K units with cus-
tomer-provided button.
• Select installation locations and models for the
ventilation units to keep noise emissions down.
• If possible, avoid:
• Sound bridges with the structure. Leave suffi-
cient distance between the other façade com-
ponents.
• Disbalances, which arise from different
lengths of control cable. Observe installation
requirements relating to cable lengths and
types.
• Incorrect measurements if the installation loca-
tion of the control and external sensors is inap-
propriate. Avoid disturbing influences and direct
sunlight.
• When using more than 2 ventilation units, we
recommend installing the room air control in an
electronic switch box to be supplied by the cus-
tomer. This provides sufficient space for the
connection of the cables to the room air control.
• Quiet changeover noises when the PPB 30
fans change direction of rotation. Do not install
PPB 30 in bedrooms.
• Soffit elements PP 45 LE and PP 45 LEV can-
not be combined with PPB 30 units.
